ILLINOIS, ASSIGNOR TO RODGER BALLAST CAR. COMPANY, OF COOK COUNTY, ILLINOIS, A CORPORA- TION OF ILLINOIS.

SPECIFICATION forming part of Letters P Application 161 July 27, 1903.

To tu whom t may concern,.-

Be it known that I, OT'ro W. MnIssNER, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Dump-Cars, of which the following is a specification.

This invention relates to that class of dumpcars known as center-dump cars, and has for its principal object the providing of a simple, economical, and efficient dumping car either or both sides and center, vas willmore fully'hereinafter appear.

The invention consists 4principally in a dump-car in which there are combined a supporting-framework having upwardly-extending side and end boards and a dumping bottorn portion formed of a central V-shaped portion extending lengthwise of the car and underneath the supporting-frame and two swinging portions pivotally secured to the framework of the car to each side of the V-shaped dumping portion and arranged to lie in a iiat plane and form flat floor-sections when carrying a load and be swung downwardly to discharge a portion of the load to each side of the car.

The invention consists,further and f1nally,in the features, combinations, and details of construction hereinafter described and claimed.

In the accompanying drawing, the figure represents a transverse sectional elevation of one type of car as it appears when constructed in accordance with these improvements.

In illustrating and describing these improvements I have only illustrated and will describe that which I consider to be new, taken in connection with so much that is old as will properly disclose the invention to others and enable those skilled in the art to practice the same, leaving out of consideration other and well-known elements which if set forth herein would only tend -to confusion, proliXity, andambiguity.

In constructing a car in accordance with these improvements I provide a supportingframework formed in any desired Way, but

DUMP-ICAR.

preferably as shown in the drawing, in which there is a plurality of transverse deck-beams a. Extending upwardly from the supportingframework of the` car are side boards I) and end boards c, secured thereto in any desirable or convenient manner.

To provide. a dumping-car which can be used for the purpose of discharging a load en- .tirely between the track-rails in a manner similar to the well-known Rodger type of car or which can be used for discharging a portion of the load to one or both sides of the track or for discharging the entire load between and to both sides of the track, as may be necessary, a centrally-disposed V-shaped hopper portion is provided, extending lengthwise of the car, with its apex extending below the supportingframe. This V-shaped hopper portion is made of one inclined side d, rigidly secured to the framework of the car, and a swinging inclined side e, which may be used as a dischargingdoor to dump material between the track-rails. To complete the dumping-bottom, two swinging sections f and g are provided and pivotally secured at'their inner lateral edges to the supporting-framework of the car at each side of its longitudinal center and also at each side of the central dumping hopper portion. These swinging sections may be used, as shown to the left of the gure, as flat bottom portions to carry a portion of any desired load, or they may be dropped down, as shown to the right of the gure, so as to discharge a portion of the load independently or simultaneously to either or both sides of the track and in connection with the hopper portion all Yof the load between the rails, all of which Will be understood and appreciated by those skilled in the art. To open and close these swinging sections which form the flat bottom, rock-shafts fand chain mechanism 7l are provided and mountedas shown in the drawings, so that the rotation of such shaft in onel direction tends to close the doors, while a rotation in the opposite direction permits them to be opened. To open and close the swinging door of the hopper portion, another rockshaft j, is provided, having chain mechanism lo wound therearound and secured to hooks Z on the lower free edges ofv such swinging door, the operations of which are well known to those skilled in this particular art.

I claiml. In a dump-car 'of the class described, the combination of asupporting-framework having upwardly-extending side and end boards, and a dumping bottom portion formed of a central V-shaped portion extending lengthwise of the car and underneath the supporting-frame and two swinging sections pivotally secured to the framework of the car to each side of the V-shaped dumping portion and arranged to lie in a fiat plane and form fiat Hoor portions and to be swung downwardly to discharge a portion of the load, substantially as described.

2. In a dump-car of the class described, the combination of a supporting-framework provided with upwardly-extending side and end boards, and a dumping bottom portion formed of a central V-shaped hopper portion extending lengthwise of the car below the supporting-frame and two swinging sections pivotally secured to the supporting-fralnework of the car to each side of the hopper portion so as to form a flat bottom and dumping scctions, substantially as described.

3. In a dump-car of the class described, the combination of a supporting-frameWork provided with upwardly-extending side and end boards, and a dumping bottoni portion formed of a centrally-located V-shaped hopper portion extending lengthwise of the car and having one fixed inclined side and 011e swinging side forming a discharging-door and two swinging sections pivotally secured at their inner edges to the supporting-framework ol the car at each side of its longitudinal center and outside of the V-shaped hopper portion so as to forni iat fioor portions for carrying a load and inclined portions to' discharge a portion of the load to each side of the car, substantially as described.
